SPECIFICATION forming part of Letters Patent No. 589,601, dated September '7, 1897'.

i Application tiled April 21, 1897. Serial No. 633,078. (No model.)

To di( infront, JmL/f concern.;

Be it known that I, `GEORGE l5. HOWELL, a citizen of the United, States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and Auseful Improvements .in Pump Tater-Closets 5 and I do hereby declare the following to be full, clear, and exact dc scription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to water-closets, but more particularly to pump water-closets for marine purposes.

When the water-closets on vessels are located below or slightly above the water-line, it is necessary to provide a pump into which the contents of the bowl are first drawn and then forced overboard, a small water-pump being operated to supply clean water to the bowlv during the discharging process. After the pum ping has ceased it becomes necessary to iill the bowl with clean water, and for this purpose it has been the practice, as far as I am aware, to provide a separate valve, which is either operated by a han d-pull or by means of a foottreadle, both of which are decidedly objectionable, for the reason that very often (owing to the more or less complicated con-V struction of marine closets generally) they are left in a foul condition or without the necessary water remaining in the bowl, owin g to the fact that the user either does not know how or does not care to take the necessary trouble to operate the necessary parts to place the closet in the proper condition. Another object-ion to closets so supplied with water is that the refill is obtained by operating the valve until the proper amount of water is supplied to the bowl. This cannot be properly ascertained while sitting upon the seat, as there is no means of measuring the quantity of water entering the bowl except by the eye, and should it be attempted to do this without watching the progress of reillin g thereis greatdanger of an overflow or an insuiiicient quantity of water being supplied to the bowl by reason of the valve not being operated for the proper length of time.

The primary object of my invention is to overcome these and other objectionable features by providing means, operated from a single source, for effecting the proper dis-V charge of the contents of the bowl, injecting clean water into the bowl while the discharge or soil pump is in operation, and `finally supplying a measured quantity of water to the bowl to be retained therein until the contents of the bowl are again discharged.

Other objects are to provide simple and efficient means for governing the supply of water to the bowl, so as to preclude all possi bility of an overflow, and to provide a simple and efficient device which may be employed in connection with various Yforms of closets and pumps.

The invent-ion will be hereinafter more particularly described with reference to the ac colnpanying drawings, which form a part of this specification, and then pointed out in the claims at the end of the description.

In the drawings, wherein similar letters of reference denote .similar parts, Figure l. is a rear view, partly in section and partly in elevation, ot' an apparatus embodying my invention. Fig. 2 is a vertical sectional view through the closet, taken on the line II II of Fig. l. Fig. 3 is a detail sectional plan view through the waterpump and waterways, taken on the line III III of Fig. 1. Fig. 4 is a side view of another form of apparatus embodying my invention; and Fig. 5 is a fragmentary rear view, partly in section and partly in elevation, of the form of apparatu shown in Fig. e.

i In said drawings, A may designate a closet of the pedestal type having the bowl c thereof provided with the usual seat and cover and supported upon a suitablebase-plate A. The lower portion of the closet-bowl is open and suitably connected to a soil-pipe a", which latter may be angular in form and connected to the lower portion of a discharge or soil pump B. This pump, as well as the closet, may be of any desired form and may have a vertically-reciprocating pistou or plunger, (shown in dotted lines in Fig. 4,) so that when the piston is operated the contents of the bowl will be drawn therein and forced through the discharge soil-pipe b overboard clear of the sides of the vessel, suitable valves (shown in dotted lines) being provided in the lower por- IOO tion of the pump-cylinder, the piston, and the discharge soil-pipe, respectively, to secure proper action of the pump.

For the purpose of supplying clean water to the closet-bowl and for automatically controlling such supply I may provide a waterpump C and a casing or cylinder D, containing an automatic valve D. This cylinder and the pump may be variously arranged with respect to each other, and in Fig. l said cyl.- inder is located above and to one side of the pump. A pipe d leads overboard or to some other source of water-suppl y and is connected to the inlet of the casing or cylinder D above the valve D', said valve preferably comprising a rod, a disk or other valve d2, arranged upon said rod and adapted to shut off the flow of water through the inlet-pipe d when resting upon the seat di, and a piston d4, adapted to move vertically in said cylinder.

The pump may be supported upon a hollow base d5 and may communicate therewith through an aperture or opening arranged below the lower open end of the pump, a clack or other valve d being provided to prevent the water entering the. pump through said opening trom being forced back into the base. This base may be connected to the cylinder D by a waterway or pipe, as at 6X7, which latter extends from said cylinder below the seat d3 and may have a portion thereof formed integrally with the pump and the otherportion formed integrally with the cylinder, or said pipe may be formed in one piece or separately from the pump and said cylinder.

At. d8 and (Z9, Figs. l and 3, are pipes or waterways, which may be formed integrally with and extend substantially parallel to said pump. One of said pipes or waterways, as d8, communicates with the base di at one end and at the other end communicates with the upper end of the pump and with the lower end of the cylinder D, while the pipe or waterway Z9 has its lower end communicating with the lower end of the pump and its upper end with the lower end of said cylinder. rlhe upper ends of the pipes or waterways ds and (Z9, where they communicate with the cylinder D, are each controlled by suitable clack or other valves di", arranged directly over said pipes, (one only of said valves being shown,) and pipe d8, where it communicates with the base d5, is controlled by a suitable valve du, while the lower end of the pipe or waterway C19, where it enters the pump7 is also provided with a suitable valve, as at e112, said waterways or pipes being of any suitable construction and arranged in any preferred manner.

The portion ot' the cylinder D in which the piston of the valve D' is adapted to slide may be located somewhat above the valves d10 and may be divided into two sections by an annular or other'opening d, which serves to connect the lower section with a chamber dm. This chamber may be annular and arranged around said lower section and may have one or more preferably small apertures C115, connecting said chamber with the space above the valves d10 and below the lower section, so that after the piston-valve D is raised bythe water forced into the cylinder D by the pump C the water above said valves dw will resist the backward or downward movement of said piston-valve and will gradually pass into the annular chamber d through said aperture or apertures d until the disk or valve LZ2 reaches its seat d3. The upward movement of the valve D may be limited in various ways or, as shown, by the rod thereof striking the cap di, arranged on the cylinder D. and instead of depending upon the weight or' the valve and pressure of the water on its upper surface for `its downward movement a suitable spring or other means may be employed to assist its return. A pipe e has one end. thereof opening into the chamber C114 and its other end suitably connected to apipe or waterway d, which latter may form a part or' the bowl and lead to or near the top thereof.

yThe pipe or waterway e may have one or more lateral rapertures e2 leading to an apertured rim or other ilushing device of the bowl and one or more apertures e3 leading to a refill-chamber e4, the latter being provided with one or more apertures e5, preferably located at or near the water-line of the bowl, so as to gradually supply the proper amount of water to the bowl after the discharging process. By this means when the pump C is operated so as to force water into the cylinder D the valve D' will be lifted and automatically suspended, so as to prevent shutting off the water whilel the pump is in action, by reason of the pressure and retarding action of the water under the piston ot' said valve, thus permitting the proper quantity of water to be constantly supplied to the bowl; but as soon as the pump ceases to operate the valvewill gradually automatically lower and shut oit' the water from the inletpipe, so as to prevent an overflow.

In order to simultaneously operate the discharge-pump B and the water-pump 0,1 may connect the upper end of the piston-rod of the pump C to an arm f, (Figs. l and 4,) eX- tending outwardly from a suitable yoke,which latter may have pendent arms extending on opposite sides of the pump-cylinder and connected to levers f2, intermediate their ends. These levers may have one of their ends pivoted to a bracket pendent from the discharge soil-pipe b or other portion of the pump and their outer ends connected by links f3 to crankarms f4, said crank-arms being` arranged on a suitable shaft f5, supported in brackets or standards extending upwardly from the baseplate A'. An operating-lever f6 is secured to the rocking shaft f5, so that as said lever is moved back and forth the levers f2 will be rocked on their pivots and a vertical reciproeating motionimparted to the yoke f and the plungers of both of the pumps. Though the IOO l'IO

means shown for operating the pistons of the pumps is very effective,it is obvious that other means may be employed when desired.

The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings.

Assuming that there is sufficient water in the waterways, lthe base d5, and the water-pump from a previous operation and the plun gers of the discharge and said water-pump are actuated by the mechanism heretofore described, it will be seen that as the plunger in the water-pump is forced downward, for instance, water previously in said pump will be forced past the valve 1,12 into the waterway d and then past the valve d10, controlling its upper end, and into the cylinder DQ The pressure of the water against the piston d4 of the valve D will raise the disk d2 ott its seat and force the piston into the upper section of the portion of the cylinder in which said piston slid es,

so as to permit the water to pass through the annular opening d int-o the chamber du. From here the water enters the pipe e and then passes up the waterway c' through the lateral openin gs into the flushing-rim and the refill-chamber c" of the closet-bowl. During the downstroke of the plunger in the water-pu mp water will flow or be drawn past the disk or other valve d2 into the base d5 and then past the valve d up the waterway d8 and into the upper end of the pump, as indicated by the arrows. The return or upstroke will open the valve d, drawing water into the pump-cylinder, and will close valve d, forcing the water above the piston in said pump past the valve d10 into the cyl.inderD,again raising the pistonvalve D', if it has lowered, and is then forced.

into the chamber d, and from there into pipe e in a similar manner tothe previous stroke of the pump-plunger. The water below the piston d* of the valve D' will gradually pass through the aperature d, so as to permit the valve d2 to graduallyautomatically rest upon the seat d3, thus shutting off the supply of water from the inlet-pipe to prevent an over- `flow and at the same time preventing the shutting off of the water while the pump is in operation. As the discharge-pump B is connected so as to operate with the water-pum p C the contents of the bowl will be drawn therein and forced through the soil or discharge pipe b overboard free of the vessel simultaneously with the forcing of clean water into the bowl by the water-pump. After the pumps cease to be operated the water in the refill-chamber will flow through the aperture or apertures e5 in the bowl, thus supplying a measured quantity of water to he left standing in said bowl.

I thus provide a simple and efficient marinel or pump water-closet by which the bowl may be simultaneously discharged and clean water forced therein during the discharging process and a proper quantity of clean water supplied to the bowl to be left standing therein after the discharge.

In Figs. at and 5 I have shown a device elnbodying my invention in which the waterpump is single-acting instead of double-acting, as in Fig. l. In this case the dischargepump and the means for simultaneously operating the water and the discharge pumps are the same as in the form already described. The cylinder F, though slightly diiferent in construction, and the piston-valve and the action of said valve are substantially the same as the cylinder D and the piston-valve D', and will therefore not be referred to in detail. The pump G and the cylinder F may have open screw-threaded lower ends adapted to iit into screw-threaded apertures or recesses in the base g, so as to be rigidly held thereon. This base has a lower waterway g' communicating with the'cylinder F below the valve-seat g2 therein by a waterway or pipe g3, and has a waterway gl arranged above the waterway g3 and beneath the pump G, an opening controlled by a suitable valve g5 being provided, so as to form a communication `between the lower waterway and said pump. The upper surface of the base may have an opening controlled by a suitable valve g, so as to form a communication between. the cylinder F below the piston-valve D and the waterway g4. The valve D', instead of being guided simply by the piston d thereof, may have its rod passed through a boss of a spider or yoke, as at 97, arranged at the upper portion of the cylinder F or secured, as shown, to the lower end of the inlet-pipe d.

The operation is substantially the same as that of Fig. l, exceptv that the pump forces Water into the cylinder F and the bowl during the downstroke only, by which movement the valve g5 is closed, the valve g opened, and the piston-valve D lifted, as shown. The water then passes into the annular chamber d and into the pipe g8, which connects said cham ber to the bowl in the manner heretofore explained. During the upstrolre of the piston the valve go is closed and Water enters the waterway g3 and is drawn past the valve g5 into the pump to be forced into the cylinder F'during the downstroke, the resist-ance of the water below the piston-valve D preventing said valve from shutting off the water during the upstroke of the pump-plunger.

It is obvious that various changes may be made in the construction and arrangement of the parts, that other means may be provided for permitting 'the gradual return of the automatic valve or arranging a valve so as to act automatically, that more than one valve may be employed, and that some of the parts may be dispensed with or others substituted therefor without. departing from the spirit of my invention.

Having thus fully described by invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
